Abstract (en)
[origin: GB2344935A] A keypad assembly comprises a keymat <B>110</B>, a switch assembly <B>12, 14, 15</B> and an intermediate element <B>160</B> positioned between the two. The intermediate element <B>120</B> is configured to provide a aperture associated with a key <B>111</B> of the keymat <B>110</B> and a resilient member <B>163, 164</B> attached to the intermediate element <B>120</B> extends into the aperture. Pressure applied to a key <B>111</B> of the keymat <B>110</B> is transferred via the resilient member <B>163, 164</B> to a key dome <B>12</B> of the switch assembly <B>14, 15</B>. Such an arrangement may be used in mobile phones having in-mould keymats to prevent neighbouring keys being simultaneously actuated.
